MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed February 14, 1920. Serial No. 358,569.

To all whom it may concern:

Be it known that I, BENJAMIN M. Knso'r, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved mechanical movement in which one revolution of a drive member imparts two complete reciprocatory movements or strokes to any desired form of driven element.

An object of the present invention is the production of a device for converting rotary movement into reciprocatory movement and vice versa, said device comprising a novel form of revoluble member having curved or cylindrical intersecting channel ways formed therein and corresponding curved or cylindrical pivot rods connected to a driving arm and arranged to operate in the aforesaid channel ways for imparting two complete reciprocations for every revolution of the revoluble member.

With these and other objects in view the invention further consists in the detailed arrangement and construction of the several parts, wherein advantages of simplicity in manufacture, and minimum costs in production are prerequisites.

In the accompanying drawings wherein similar reference characters designate cor responding parts in the several views Figure 1 is an elevation of my improved mechanical construction;

Fig. 2 is a longitudinal sectional view through the device the same having been taken on the line 2-2 of Fig. 3;

Fig. 3 is a similar view of Fig. 1 showing the parts in a different position;

Fig. 4 is a transverse sectional view on the line H of Fig. 3; and

Fig. 5 is a similar view to Fig. 4: showing another form of channelway and sliding pivot block.

The present invention has been designed to take the place of many forms of complicated interconnected mechanical elements now in use, and to that end consists of a revoluble driven member 1, in which is formed a series of cylindrical channelways 2 and 3 intersecting each other at right angles as clearly shown in Fig. 1. These channelways are preferably bored from the drive member 1 and are so arranged as to extend into one face of the drive member as shown, thereby producing diametrical openings 4 allowing for the pivot connections and operation thereof. The cylindrical channelways 2 and 3 extend into the periphery of the revoluble member 1, and are adapted to receive cylindrical pivot rods 5 and 6, respectively. These pivot rods are slid into the channelways from the periphery of the revoluble member 1 and are prevented from coming out by the overlying edges of the face of the drive member as will be understood.

Each pivot rod is provided with an opening 7 through which extends a securing bolt 8 to be connected to a driving arm 9 which in turn is adapted to impart the reciprocatory movement from the revolving drive member 1. The bolts 8 are formed with heads 10 and reduced end portions 11. A

lock nut 12 is shown as securely fastening the driving arm 9 to the pivot rod. The head 10 of the bolt is machined to correspend with the curved channelway.

The driving arm 9 is freely movable about the reduced portions 11 of the bolts 8 and is spaced from the face of the revoluble drive member 1. A shoulder 13 is formed on the bolt 8 and it is against or upon this shoulder that the arm 9 is supported. The shoulder 13 substantially alines with the upper face of the pivot rod which projects above the face of the revoluble drive member.

The driving arm 9 may be connected to any form of apparatus which it is desired to drive and a conventional rod or driven element 14 is shown as connected to the arm 9 at 15.

In operation, the driven element 14.- is reciprocated twice during a single revolution of the drive member 1, the pivot rods 5 and 6 sliding back and forth in their respective cylindrical channelways 2 and 3. In like manner the arm 1d might be utilized to drive the revolving member 1 should the mechanical adaptation of the device make it necessary. The movement of the pivot rods in the cylindrical channelways reduces the friction to a minimum, and in addition permits of a certain compensation due to any rolling action that the device might be subjected to. For example, in mechanical structures where certain Wabbling tendencies are manifested, the utilization of this form of pivot rod proves highly advantageous.

As instances of the foregoing, the use of a movement of the class described will be found readily adaptable to motor driven tire and other pumps, oiling systems, sewing machines and the like, and I do not limit myself to any particular device to which it may be applied.

The modified form set forth in Fig. 5 discloses the use of a pivot block 15 as dis tinguished from the pivot rods heretofore described. This form of block may be useful in some types of machinery where it is desirable to maintain a stabilized connection, as distinguished from the compensating movement heretofore referred to.

Various changes in the form and con: struction of my invention may be resorted to and I do not limit myself to the exact construction herein set forth.

I claim 1. In a device of the class described the combination with a revoluble drive member having cylindrical channelways bored therein, and intersecting each other at right angles, of a cylindrical pivot rod movable in each cylindrical channelway, and a driven arm freely connected to each pivot rod and spaced from the face of said revoluble drive member, whereby all rolling and wabbling tendencies of the aforesaid revoluble drive member or the driven arm are compensated for.

2. In a device of the class described the combination with a revoluble drive member having two diametrically disposed cylindrical channelways bored therein and extending into one face of the said drive member, of a cylindrically formed pivot element slidably mounted in each of said channelways, a bolt extending through each cylindrical pivot element beyond the face of the drive member and a driven arm freely mounted upon the bolts and spaced from the revoluble drive member.

3. In a device of the class described the combination with a revoluble drive member having two diametrically disposed cylindrical channelways bored therein and extending into one face of the said drive member, of a cylindrically formed pivot rod slidably mounted in each of said channelways, a bolt extending through each cylindrical pivot rod having a shoulder formed thereon and extending beyond the face of the drive member, and a driven arm freely mounted upon said bolt and against the said shoulder in spaced relation from the rev olnble drive member.

In testimony whereof I afiix my signature in presence of two subscribin witnesses.

BENJAMIN KESOT.
